Fig. 1 is a flowchart illustrating a video classification method according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the method includes steps 101 to 103.
In step 101, a classification tag of a target video is acquired as a first tag. The target video may be any form of video that requires tag classification. For example, the video may be a short video published by a user in a short video platform, or a long video published by a user in another video platform.
In step 102, if the number of play times is higher than a first preset play amount threshold, determining, by using a first video classification model trained in advance, a prediction tag of the target video as a second tag.
The number of plays can be determined according to the number of times recording rules of different video platforms, and the specific method for determining the number of plays is not limited in the present application.
And under the condition that the playing times are higher than the first preset playing amount threshold, the playing times of the target video can be represented to be higher, namely, the first preset playing amount threshold can be used for screening out the target video with higher playing times as the video for predicting the second label.
The first video classification model used to determine the second tag may be any video classification model as long as a predictive tag of the target video is available.
In step 103, in the case that the second tag is not the same tag as the first tag, determining the classification tag of the target video as the second tag.
And carrying out secondary label prediction on the target video with higher playing times, thereby improving the label accuracy of the target video with higher playing times.
The class label as the first label of the target video may be a class label determined by any means. For example, the method shown in fig. 2 may be used.
Fig. 2 is a flowchart illustrating a video classification method according to still another exemplary embodiment of the present disclosure. As shown in fig. 2, the method further comprises step 201 and step 202.
In step 201, determining the classification tag of the target video by a second video classification model;
in step 202, the classification label of the target video is taken as a first label.
The second video classification model and the first video classification model are different video classification models. The video classification model may be different video classification models obtained by training different training samples of the model, different video classification models obtained by adopting different video classification methods, or different video classification models obtained by adopting different neural networks, so long as the video classification model is not the same as the first video classification model.
In a possible implementation manner, the training data of the second video classification model may be sample video with play times and/or without play times. That is, the training data of the second video classification model is random annotation data.
Through the technical scheme, the video classification labels of videos without playing frequency information or videos with fewer playing frequency can be determined through any video classification mode, such as the mode of the second video classification model, so that any video can be ensured to obtain the corresponding video label as the first label; and after the playing times are higher than the first preset playing amount threshold, the target video can be subjected to video classification label re-prediction in a mode different from that of determining the first label, for example, the first video classification model is used for determining, so that a second label of the target video is obtained, and the video classification label to which the target video belongs is corrected according to the second label, so that the accuracy of the classification label of the target video with higher playing times can be ensured.
In another possible implementation manner, the training data of the first video classification model is a sample video with a playing frequency higher than a second preset playing amount threshold. That is, when training the first video classification model, all training video data used is a high play amount sample video. Thus, since the effect of the machine learning model is affected by the data distribution, and the learning of the machine learning model can only be performed on a certain fixed distribution, the machine learning model works best on a distribution similar to the training set. Therefore, the first video classification model can have better label prediction effect on the target video with the playing times higher than the second preset playing amount threshold value through limiting the playing times distribution of the training data of the first video classification model.
For example, the applicant finds that in most short video platforms, if a plurality of short videos with fixed time length are uploaded and then are in different playing times, the distribution in the video content of the short videos has larger difference, for example, in videos with lower playing times, the content of the video is single, the information amount is not high, and in videos with higher playing times, the content proportion of scenario deductions, knowledge science popularization and the like with higher information content is obviously improved. There is some difference in video content between different play times distributions. Therefore, if the training data for training the first video classification model is limited by the threshold according to the playing times, the classification prediction performance of the first video classification model obtained by training in the target video in the distribution of which the playing times are higher than the first preset playing amount threshold is better, and the accuracy is higher.
The first preset play amount threshold and the second preset play amount threshold may be set to be completely identical or two similar different thresholds according to practical application, so long as the label classification prediction effect of the first video classification model on the target video higher than the first preset play amount threshold can be achieved, and the label classification effect is better than the classification effect of the first label for predicting the target video. For example, the second preset play amount threshold may be set relatively lower than the first preset play amount threshold, so long as the play times higher than the first preset play amount threshold are included in the play times higher than the second preset play amount threshold, and the specific value is not limited in the disclosure.
Fig. 3 is a flow chart of a method of training the first video classification model in a video classification method according to yet another exemplary embodiment of the disclosure. As shown in fig. 3, the method comprises steps 301 to 303.
In step 301, a sample video with the number of plays higher than the second preset play amount threshold is obtained. The number of plays may be determined according to the play count recording rules for different video platforms.
In step 302, the sample video is labeled with a class label. The mode of classifying and labeling the sample video can be manual labeling. In the case where the first tag of the target video is determined by the second video classification model, for example, the classification labels of the sample videos in the training data of the second video classification model may be manually labeled.
In step 303, the first video classification model is model trained by the sample video with the classification label labels.
Fig. 4 is a block diagram illustrating a video classification apparatus according to an exemplary embodiment of the present disclosure. As shown in fig. 4, the apparatus includes: an acquiring module 10, configured to acquire a classification tag of a target video as a first tag; the determining module 20 is configured to determine, when the number of play times is higher than a first preset play amount threshold, a predicted tag of the target video as a second tag through a first video classification model that is trained in advance; and the correction module 30 is configured to determine the classification label of the target video as the second label if the second label is not the same label as the first label.
Through the technical scheme, the video classification labels of videos without playing frequency information or videos with fewer playing frequency can be determined through any video classification mode, such as the mode of the second video classification model, so that any video can be ensured to obtain the corresponding video label as the first label; and after the playing times are higher than the first preset playing amount threshold, the target video can be subjected to video classification label re-prediction in a mode different from that of determining the first label, for example, the first video classification model is used for determining, so that a second label of the target video is obtained, and the video classification label to which the target video belongs is corrected according to the second label, so that the accuracy of the classification label of the target video with higher playing times can be ensured.
In one possible implementation manner, the training data of the first video classification model is a sample video with a playing frequency higher than a second preset playing amount threshold.
In one possible implementation, the first video classification model is trained by: acquiring the sample video with the playing times higher than the second preset playing quantity threshold value; performing classification label labeling on the sample video; and carrying out model training on the first video classification model through the sample video with the classification label labels.
In one possible implementation, the acquisition module 10 includes: the first acquisition sub-module is used for determining the classification label of the target video through a second video classification model; and the second acquisition sub-module is used for taking the classification label of the target video as a first label.
In a possible implementation manner, the training data of the second video classification model is a sample video with play times and/or no play times.
